after today's vote, president obama might also agree. >> obama: the filibuster historically has been used selectively for a handful of issues to extend debate. we don't have a 60 vote rule. that's become common practice. >> john: it ain't over until it's over. the senate will likely vote again on the nomination when it returns for a much-needed 10-day recess. if you're wondering why the unprecedented event took place some say they're blocking haigle to squeeze the white house for more information on the benghazi attack, something hagel has nothing to do with. others are backing ted cruz's calls for additional information on hagel's speeches and business deals. but senator john mccain may have gotten it right when he explained the vote to fox news. >> there's a lot of ill will toward senator hagel because when he was a republican, he attacked president bush mercilessly at one point said he was the west president since herbert hoover. said that the surge was the worst blunder since the vietnam war which is nonsense. and was very anti- his own party and people. people don't forget that.
